Original Paper


Single crystal LiNi0.6Mn0.2Co0.2O2 cathode materials with excellent electrochemical properties were synthesized by adjusting the calcination, ball milling, and reheating procedures. The results showed that the particle size of single crystal material obtained by the optimization method was 1.2–4.4 μm. And the material exhibited a superior discharge capacity of 190.1 mAh g−1 with high capacity retention of 96.0% after 50 cycles at 1.0 C. And the material had a discharge capacity of 162.6 mAh g−1 at 5.0 C with the capacity retention of 83.0% compared with its capacity at 0.1 C. The diffusion coefficient of lithium ions in the single crystal material reached to 10−13 cm2 s−1 after 50 cycles. By proper reheating process, the particle morphology was optimized to form a smooth particle surface, and the lattice arrangement was more orderly, which was conductive to improving electrochemical performance of the material.
